Pet Accuracy Recorder is a small addon to record misses and hits in Pet Battles to check for accuracy problems on Blizzard's end.
What It Does:
Basically, it records all misses and hits for all abilities at all accuracies silently. When you type "/PAR" then it will give you two numbers: the expected accuracy (what percent of moves SHOULD have hit) and the true accuracy (what percent of moves ACTUALLY hit). If your true accuracy is constantly lower than your expected accuracy, it probably indicates something wrong with the system.
Additionally, the addon now shows the data in the tooltips in the following format - "Effect # - Expected / Actual".
If you want to see ALL of the data, type "/dump PARData" or navigate to the file mentioned below.
Notes:
It's possible there are remaining abilities that could throw the data off, so this isn't foolproof, but it does record everything. That means if it says there is something wrong and you think there is something wrong, we can open up the data file in "World of Warcraft\WTF\Account\yourname\SavedVariables\PetAccuracyRecorder.lua" and selectively exclude the abilities that may be mucking up your data.
Also, the addon will ignore all data concerning the following: conditional abilities (ones that have a higher chance to do things depending on the weather), multi-turn abilities (like Rampage and Mana Surge), and abilities that Blizzard doesn't report correctly (Dark Simulacrum and Cyclone).
If your data gets corrupted or makes no sense and you need to reset it, type "/PAR reset".
